Changing a smartphone is often accompanied by anxiety about the safety of personal information, and instant messengers take first place in importance here. Losing years of chat history with loved ones or business partners can be a real disaster, especially if important documents or memories are stored in chats. Fortunately, the ecosystem Android and the messenger itself WhatsApp offer several reliable methods of data migration, however, each of them has its own nuances that must be taken into account before starting the process.
In this article we will analyze in detail all available transfer methods: from standard cloud recovery via Google Drive to advanced options using local backup files. You'll learn how to avoid common mistakes, such as being tied to an old number or incompatible app versions, and you can safely move to a new device without losing a single message.
The migration process requires attention to detail, especially when choosing an account and checking free storage space. An incorrect sequence of actions can lead to the old backup being overwritten with an empty file, so strictly follow the algorithms described below for a guaranteed result.
Preparing the old device for data transfer
The first and most critical step is to create an up-to-date backup on your current smartphone. Without this step, any further actions on the new device will be pointless, since there will simply be nothing to restore. Make sure that the latest version of the application is installed on your old phone WhatsApp, available in Google Play Market, since older versions may lack the necessary encryption protocols or backup functions.
Next, you need to check the backup settings inside the messenger. Go to the settings menu, select the “Chats” section and go to the “Chat backup” item. Here you will see the date and time of the last save, as well as the size of the archive. If the last copy was made a long time ago, press the button Backup manually and wait for the process to complete.
⚠️ Attention: Make sure that you are using the exact Google account that you plan to access on the new phone. Switching the account after creating a backup will make the file unavailable for restoration on the new device.
It is also important to pay attention to the automatic saving frequency settings. To be on the safe side, it’s best to select daily backups, but be sure to do a manual save before moving. This ensures that all messages received in the last few hours are archived.
☑️ Prepare your old phone
Setting up backup to Google Drive
The main tool for transferring data between devices based on Android is cloud storage Google Drive. This method is most convenient for most users, as it does not require connecting cables or using a computer. However, for it to work successfully, you must meet a number of prerequisites regarding network settings and access rights.
In the backup menu, you can choose the frequency of saving data: daily, weekly or monthly. You can also configure the “Via network” option here by selecting the “Via Wi-Fi only” option. This is critically important, since a backup copy of chats with media files can take up several gigabytes, which will quickly exhaust your mobile traffic limit.
The system will prompt you to select a Google account to save the data. If several accounts have been added to your phone, carefully check which one is selected as the main one for backup. It is under this login that you will need to log in on the new smartphone to see the available files for recovery.
| Settings parameter | Recommended value | Impact on the process |
|---|---|---|
| Copy frequency | Daily | Minimizes data loss in case of breakdown |
| Network type | Wi-Fi only | Saves mobile traffic |
| Video files | Enabled/Disabled | Significantly affects the backup size |
| Google Account | Primary | Determines the availability of a copy on a new device |
It is worth considering that WhatsApp backups to Google Drive do not take up space in your storage quota if they were created correctly through the app interface. However, if you use third-party tools to back up your entire phone, these files may count toward your total limit.
If you're low on Google Drive space, before creating a full backup of your chats, delete old unnecessary files or temporarily disable video saving in WhatsApp backup settings.
Restoring chats on a new Android smartphone
After the backup has been successfully created on the old device, you can begin setting up the new phone. The recovery process starts automatically when you first install and configure the application, but requires strict adherence to the sequence of actions. The most important rule: do not activate WhatsApp on a new phone until you are sure that the old backup is ready and available.
Install the application WhatsApp from the official store Google Play. When you launch it for the first time, the setup wizard will ask you to enter a phone number. It is extremely important to enter the same number that was used on the old device, since the encryption keys are tied to it. Using a different number will make the old backup unreadable.
After confirming the number via SMS code, the system will automatically detect the backup in your Google account. A message about the found archive will appear on the screen, indicating the date it was created. You will be prompted to click the Restorebutton. If you skip this step and click "Skip", you will lose the ability to restore chats when you first install them, and you will have to reinstall the application.
⚠️ Attention: Never click the "Skip" button when prompted to restore a backup if you want to save your chat history. Canceling this action will result in the installation of a “clean” version of the messenger without old chats.
The recovery process may take from several minutes to several hours, depending on the size of the archive and the speed of the Internet connection. During this time, it is advisable to keep the screen on and not minimize the application to avoid losing the connection. Once the downloading of messages is completed, downloading of media files will begin, which can continue in the background.
Transferring data through a local backup
Sometimes using cloud services is impossible due to the lack of stable Internet or lack of disk space. In such cases, the local transfer method comes to the rescue, which involves physically copying the database file from the old phone to the new one. This method is more labor-intensive, but gives full control over the process and does not depend on Google servers.
Local copies are created automatically every morning at 2:00 am and are stored in the internal memory of the device or on the SD card in the folder /Android/media/com.whatsapp/WhatsApp/Databases (on new versions of Android) or /WhatsApp/Databases (on old ones). The file usually has a name like msgstore.db.crypt14, where the numbers indicate the encryption version.
To transfer, you will need to copy this file to your computer or directly to a new smartphone. If you're using a new phone with a modern version of Android, the folder structure may have changed, so it's important to place the file in the correct directory before installing the app. If the folder does not exist, create it manually, respecting the case of letters in the name.
Subtleties of encryption versions
Backup files are encrypted, and the decryption key is stored inside the system. When transferring a file to another device, the key may not work unless you are also transferring system data or using root access. However, when installing WhatsApp on a new device with the same phone number, the application is often able to recognize the file if the encryption protocol version is the same.
After placing the file in the desired folder, install WhatsApp, confirm the number and wait for a message that a local copy has been found. The system will prioritize a local backup if it is newer than the cloud backup, or will offer to select it if the cloud search did not produce results. This is a reliable way to transfer data between phones from different manufacturers without using the cloud.
Use of proprietary utilities
Many large smartphone manufacturers, such as Samsung, Xiaomi i Huaweiare developing their own data migration tools that can transfer settings and data from applications, including WhatsApp. These utilities often use a direct connection via Wi-Fi Direct or a USB-C cable, which provides high transfer speeds. For example, device owners can use the app. When you connect your old and new phones, the app will prompt you to select data to transfer. If both devices support the WhatsApp migration function, the data will be transferred along with the chat history, and the current version of the messenger will be installed on the new device.
For example, device owners Samsung can use the application Smart Switch. When you connect your old and new phones, the app will prompt you to select data to transfer. If both devices support the WhatsApp migration feature, the data will be transferred along with the chat history, and the latest version of the messenger will be installed on the new device.
However, it is worth remembering that the compatibility of such tools is not always absolute. Transferring from Android to iPhone or vice versa via proprietary utilities often requires special cables and support from WhatsApp itself, which was introduced relatively recently. Always check the official documentation of the manufacturer of your new smartphone before starting the procedure.
The advantage of using proprietary utilities is that they transfer not only the message database, but also notification settings, blacklist and pinned chats. This allows you to get a complete copy of the working environment on the new device without the need to manually configure each parameter.
Proprietary utilities (Smart Switch, Mi Mover) are the fastest transfer method, but they require both phones to be turned on and located next to each other during migration.
Solving common problems and errors
Even if all instructions are followed, users may encounter technical glitches that prevent successful data recovery. One of the most common problems is the message “Backup not found,” even though you are sure you created one. Most often this is due to the fact that you are signed into a different Google account on the new phone or have not given the application permission to access the storage.
Another difficulty arises when application versions do not match. If your old phone was running a beta version of WhatsApp or a very old build, the new phone may not recognize the database format. In this case, it is recommended to first install the same version of the application as before, restore the data, and then update to the current version through the official store.
Also, users often complain about the recovery process freezing at the “Preparing” or “Download” stage. This could be caused by an unstable internet connection or low RAM on your new device. Try rebooting your phone, clearing the app cache (if you already have it installed), and trying again, making sure you're connected to a reliable Wi-Fi network.
⚠️ Attention: If you factory reset your new phone during a failed restore attempt, make sure your old Google Drive backup wasn't overwritten by a blank file from your new device. In critical situations, it is better to temporarily disable the Internet on the new phone before setting it up.
In cases where nothing helps, it is possible to contact WhatsApp support, but they do not restore data remotely. The only way out is to search for local copies on the old device or use third-party software for reading databases, which requires high qualifications.
Frequently asked questions (FAQ)
Can I transfer chats if I changed my phone number?
Yes, this is possible, but the procedure must be performed on the old one phone before transferring to a new one. In WhatsApp settings on your old device, use the “Replace number” function. This will transfer your history and profile to the new number, after which you can create a backup and restore it on a new phone under a new number.
What to do if the backup is too large and does not load?
Try creating a new backup on your old phone, excluding video files from it. In the backup settings, uncheck the “Enable video” option. This will significantly reduce the archive size and speed up the download process on the new device. The photos will be saved.
Will my chats disappear from my old phone after the transfer?
No, the data on the old phone remains untouched until you delete the application yourself or reset the settings. However, due to encryption, you will not be able to use the same WhatsApp account on two phones at the same time. When activated on a new device, the session on the old one will be ended.
Is it possible to restore chats from iPhone to Android?
Yes, starting in 2021, WhatsApp supports the official transfer of chats from iOS to Android. This requires a Lightning to USB-C cable (or adapter) and using the migration feature when you initially set up your new Android smartphone (available on many Samsung, Pixel, and other models). Simply copying files via a computer will not work in this case due to different file systems and encryption.
